Hello,
When you first enabled two-factor authentication, you were given a backup code. If you took a screenshot or saved the code elsewhere, find it and use it to sign in to your account.
If you lose your phone, the backup code will help you get into your account. Unfortunately, if you no longer have access to the Phone number or a backup code, you will no longer be able to sign in, and you may lose access to this account, as Microsoft doesn't provide any other ways to verify your identity.
You may have to create a new account with another number that you currently have active.
